[@Ashifili] Yeah but think of it this way for Eiko, she makes more clones then the population then everyone gets a free shotgun because you just need one shot from a shottie and the clone's dead.  And if Eiko were to do it, she'd probably go into a coma or have a seizure and become nothing but the mind of all of the clones she made and wouldn't be able to make more, so yeah if she did it she'd probably die or go into a coma, but live as their hive mind in a way. 

For Gaz he just needs to focus and he'd be on Goku levels of strength, but it's a good thing he's the way he is, because if he ever learned he's one of the strongest then he'd be on clutch to make sure he learns everything to be on a god's level of power, but he already thinks he's bullet proof so everyone keep it quiet that he's powerful. 

Also when I think about it if someone with Gaz's skills came at him and tried to copy his move of copying moves he'd probably turn into a black hole or explode and destroy the universe.
